Storyline : Balls-out “60 Minutes” producer Lowell Bergman sniffs a story when a former research biologist for Brown & Williamson, Jeff Wigand, won’t talk to him. When the company leans hard on Wigand to honor a confidentiality agreement, he gets his back up. Trusting Bergman and despite a crumbling marriage, he goes on camera for a Mike Wallace interview and risks arrest for contempt of court. Westinghouse is negotiating to buy CBS, so CBS attorneys advise CBS News to shelve the interview and avoid a lawsuit. “60 Minutes” and CBS News bosses cave, Wigand is hung out to dry, Bergman is compromised, and the CEOs of Big Tobacco may get away with perjury. Will the truth out?
